Twelve days of multiple tornadoes in the U.S.

Last such stretch in 1980

It has been a nasty 12 days in parts of the U.S.

At least eight tornadoes have touched down each day.

There were 27 twisters reported Tuesday; Kansas City and parts of Indiana and Ohio were the targets with tornado warnings reaching as far east as New Jersey and New York City.

One person was killed more than a hundred hurt.

High pressure over the southeast and an unusually cold trough over the Rockies have forced warm, moist air into the central U.S. triggering repeated thunderstorms and raising the spectre of tornadic activity.

Forecasters say there is no end in sight to this pattern of storms.

In the past 30 days, there have been more than 500 tornado reports across the country. There are only four other recorded instances when more than 500 U.S. tornadoes were observed in a 30-day period: in 2003, 2004, 2008 and 2011
